Pipe ffmpeg stream to sox rec [closed]
8 novembre 2023, par Red-Tune-84I am reading an audio stream via ffpmeg like this :



ffmpeg -i http://icecast.radiovox.org:8000/live.ogg -f mp3 filename



and want to pipe it to a sox command :



rec filename rate 32k silence 1 0.1 3% 1 3.0 3%.



Ultimately, what I am trying to achieve, is to record the audio from a live Icecast stream of a talk show. I only want recordings though of the individual's speaking. Everytime there is silence, I want to stop the recording and start a new one once they start speaking again.

ffmpeg seems to be capping my output
11 septembre 2012, par Kurt SpindlerI'm trying to extract individual frames from a video.
ffmpeg -i face_source.wmv face_sourceframes/image%03d.jpg
is almost working just fine. The first six or so appear perfect (have roughly 30kB file size), but then they continuously degrade (e.g. 23kB, 17kB, etc.) until all frames are 11kB. Of course, these frames are pixelated and not desired.
I tried forcing a bitrate with the
-b
option. ffmpeg tells me this about the inupt video :Duration: 00:00:10.07, start: 0.000000, bitrate: 781 kb/s
So I set bitrate, first using
-b 781k
, and then, just to be safe, also tried doubling it, to-b 1562k
. Neither of these options made any apparent difference in the output.Any help would be appreciated ! Thank you !

lavc : add a header for internal generic-layer APIs
20 juin 2023, par Anton Khirnovlavc : add a header for internal generic-layer APIs
The goal is to distinguish between APIs provided by the generic layer to
individual codecs and APIs internal to the generic layer.Start by moving ff_decode,encode_receive_frame() and
ff_decode,encode_preinit() into this new header, as those functions
are called from generic code and should not be visible to individual
codecs.
